Blogger Custom Domain With a Go-daddy Account. Hi Friends, converting a blog to Custom domain is very easy (because, the
complete hosting procedure will be taken care by the blogger itself),
but if you buy a domain from GoDaddy or other webhosting services, then
you have to manually create the settings in the blogger as well as in
your domain manager. This is a very easy step. Just follow the steps
below.

6. Now, Log into your GoDaddy Account & Go to Domains -> My Domains{Domain Manager}.
7. Click on your Sitename & Open Nameservers Link.
8. Enter [NS09. DOMAINCONTROL.COM] for Nameserver 1 and [NS10.
DOMAINCONTROL.COM] for nameserver 2. Make sure, you selected Custom
name servers.
9. Now, Click on Total DNS Control and MX Records.
10. Delete any existing A records if any (the ones at the top)
11. Click on "Add New A Record".
12. Enter the details as shown in below figure & Click OK.
13. Delete the CNAME that has a Host of www
14. Click Add New CNAME Record
15. Put www in the Enter an Alias Name field, ghs.google.com in the
Points to Host Name field and leave the TTL as 1 Hour.

Click on OK.

NOTE: The settings may take 1 hour to be saved and to be worked. It's Very Easy to Set Up Blogger Custom Domain Using Godaddy if you follow all the above said instructions.
